In a subsea production environment, a HIPPS (High Integrity Pressure Protection System) is used to operate the system at a design pressure lower than the Shut-in tubing pressure. It helps maintain high reliability against overpressure or burst scenarios. This paper introduces a subsea HIPPS system and its application principle. It also discusses how HIPPS can be an enabler for developing high pressure remote or stranded fields. Furthermore, it discusses the perceived hardware/project cost reduction benefits, which may or may not be available or are insignificant. From experience on multiple field development projects, HIPPS is an enabler for connecting differently rated systems; however, monetary savings are not a given and vary from field to field. Attention must be given to total installed costs of the system before associating monetary gains with the introduction of HIPPS. The content and scenarios presented in this paper pertain to deep-water field developments.
